This is a domestically produced semi-dry wetsuit meticulously crafted with attention to sewing, specifications, and details. The sponge is based on the highest grade DT sponge from National Rubber Co., Ltd., Japan's largest manufacturer, which is also used by famous overseas and domestic brands. For the outer jersey of the gussets (underarms, crotch, buttocks) and the back of the knees, we use a super-stretch jersey (relaxation jersey) jointly developed with a renowned Japanese textile company, offering excellent texture and elasticity. The suit's brushed lining uses one of Japan's leading highest-grade brushed materials, known for its quick-drying, mobility, heat retention, and cost-effectiveness. For enhanced comfort during surfing, this semi-dry suit comes standard with an inner neck. By equipping the inner neck, we have achieved improved heat retention by preventing water entry, which was a problem with traditional designs. We are committed to producing this suit with attention to every detail to ensure customer satisfaction. #surfing #wetsuit #semidrysuit #fullsuit #longjohn #backzip #nonzip #chestzip #longchestzip #airflameboost ML Size Details 1 Height 172 2 Weight 62 3 Neck Circumference 36 4 Shoulder Width 44 5 Chest Circumference 92 6 Waist Circumference 72 7 Hip Circumference 88 8 Back Length 67 9 Sleeve Length 75 10 Upper Arm Circumference 28 11 Elbow Circumference 24 12 Forearm Circumference 26 13 Wrist Circumference 16 14 Inseam 70 15 Below Knee Circumference 31 16 Calf Circumference 34 17 Ankle Circumference 21 (Notes) 1 Please note that we cannot accept cancellations, returns, or exchanges due to customer convenience. 2 If you have any questions, please be sure to ask before purchasing.
